Question

How are ions formed?

A. by the disintegration of one or more electrons
B. by the sharing of one or more electrons between two atoms
C. by the transfer of one or more electrons from one atom to another
D. by the disintegration of one or more protons

Answer 1

Hey there!

Your answer is c. by the transfer of one or more electrons from one atom to another.

Ions can be positive or negative. Positive ions are called cations, and negative ions are called anions.

Electrons are transferred because two atoms have a large difference of electronegativity and the electrons are shared so unequally that the electrons are completely transferred from one atom to another, forming ions.

Hope this helps!
